Brainstem death is a clinical syndrome defined by the absence of reflexes with pathways through the brainstem – the "stalk" of the brain, which connects the spinal cord to the mid-brain, cerebellum and cerebral hemispheres – in a deeply comatose, ventilator-dependent patient.Identification of this state carries a very grave prognosis for survival; cessation of heartbeat often occurs within a few days, although it may continue for weeks if intensive support is maintained.

  • موت جذع الدماغ هو متلازمة سريرية تُعرّف بغياب المنعكسات المتعلقة بالمسارات العصبية التي تمر عبر جذع الدماغ؛ «سُوَيقة» الدماغ التي تربط الحبل الشوكي بالدماغ المتوسط ونصفي الكرة المخية والمخيخ، في مريض فاقد للوعي ومعتمد على جهاز التنفس الصناعي. يحمل تشخيص هذه الحالة إنذارًا سيئًا للغاية للبقيا؛ غالبًا ما يحدث توقف لنبضات القلب في غضون بضعة أيام، ولكن من الممكن أن يستمر النبض لأسابيع إن وُضع المريض تحت عناية مركزة بدون انقطاع.
  • 腦幹死亡（brainstem death）是死亡的其中一種定義，指腦幹已經不再運作，喪失控制其他器官的功能，包括無法自行呼吸。 在香港等普通法地區中，醫生會為病者進行兩次多重腦幹測試，如果第二次測試後，病者仍沒有生命跡象，那刻便成為證實死亡時間。 在科學上，人的腦幹死亡後，將不能夠復原，原因是因為腦幹細胞都是不可再生的細胞，細胞死後沒有其他細胞會分裂以回充死亡的細胞，而腦幹對比大腦，體積明顯小很多，因而難以像大腦死亡一樣，能重新復原，而且腦幹死亡也意味著自身控制的能力消失，所以難以重新復原。
